The invention relates to a self-short-circuit push-against electrical connector, wherein a plurality of plug reeds are evenly distributed on the inner wall of a head shell, a plug push plate is penetrated on the inner wall of the head shell, a plug spring is arranged between the plug push plate and the tail of the head shell, and a plug short-circuit ring is arranged on the plug push plate. An innwall of that seat housing is connected with an inner push plate of the socket, the upper circumference of the inner push plate of the socket is connected with a plurality of socket springs, the outerlocking sleeve of the seat housing is provided with a locking sleeve, the tail of the socket outer push plate is connected with a circumferential gap between the head of the seat housing and the headof the locking sleeve, a socket spring is arranged between the tail of the socket outer push plate and the seat housing, and a socket short ring is arranged on the inner wall of the head of the socket outer push plate. The socket is plugged into the plug by the corresponding plug pusher plate of the socket pusher plate. The connector does not need external short-circuit components and is self-short-circuited without plug-in, and has high safety performance.
